I applied online. The process took 1+ week. I interviewed at Waitrose (London, England) in Nov 2015
Interview
Very friendly interviewer, I had an individual interview in which they asked introductory questions about myself, and then some questions relating to customer service and quality. Then I had a group interview where we basically just discussed things in teams. Overall i had a positive experience, and the interview was not too difficult.
Interview questions [1]
Question 1
Describe an instance in which you have had to challenge authority.
Very enjoyable, group interview session that lasted a couple of hours, it was a new store so they needed lots of hires so felt more achievable. Very casual and relaxed and spoke about the different roles on offer.
